Instapaper, arguably the most popular and well liked read it later service around, will soon be facing some serious competition on iOS. Readability announced via their blog today that not only are they finally offering their (basic) service for free, but that it’s also coming to iDevices:

With this release, Readability is available at no cost. Sign-up and youâ€™ll have your own profile and reading list in no time. Both Readability accounts and our companion apps will always be completely free, but we also offer a premium experience for users who want additional features and an easy way to support their favorite writers and publishers.

Readability is on its way to the iTunes App Store. Our new apps for the iPhone and iPad are free and undeniably beautiful. Weâ€™ve partnered with the design wizards at Teehan+Lax to deliver a simple, elegant experience featuring exclusive typography from some of the best in type: Hoefler & Frere-Jones. Thereâ€™s never been a better way to read the web on iOS. Readability for iOS is submitted and awaiting approval from Apple.

Readability strives to provide users with a seamless reading experience on the web. Like Instapaper, you can save articles for viewing at a later time, and similar to Safari’s Reader functionality, the Readability bookmarklet allows you to strip away all the excess found on a webpage and be left with only a column of text. The new free account allow you to view up to 30 of the most recent articles you’ve saved. Meanwhile, the Premium account will cost a minimum of $5 per month (works much like a donation system), where 70% of it will go towards the publishers you’ve chosen to consume on Readability.

The app store hosts many decent RSS news reader apps. None (to my knowledge) have dethroned Reeder (TMA review)Â as king of them all yet. Mr. Reader, however, showed up a couple months ago and it’s one of the first I’ve seen in a while to challenge the king.

Instapaper (TMA Review), the most popular “read it later” service on the web and for mobile devices (also an essential app on my iDevice), has received its biggest update ever. With Instapaper 3.0, you can now follow other Instapaper users and check out articles they’ve “liked”, or simply browse through Instapaper’s Editor’s Picks. Friends can be added via an email address, Facebook or Twitter. Other new features and improvements include:

If you’re new to Instapaper, it really is a fantastic tool that lets you save articles you come across on the web for viewing later (and offline). Simply visitÂ instapaper.com to get started and sign up for your free account. As with previous versions, Instapaper 3.0 is a universal app ($4.99) and the update is free for those who’ve already purchased it.

I watch a lot of technical blogs to get different perspectives on interesting news and for the occasional gems I find there. I don’t have time, however, to read or even scan them all every day and sometimes won’t browse through some of them for weeks. They’re just handy to have around.

The downside is that they clog up my newsreader and slow things down while waiting for refreshes. I don’t want to unsubscribe and lose them, so what do I do?

Enter TechWire, a free app that collects many of the most popular technical blogs in one place!

For those of you who’ve played Epic’s amazingÂ Infinity Blade (TMA Review), Penny Arcade sheds some light into the whole repetitive (yet highly addictive) bloodlines premise with its “The Perils Of Lineage” comic strip. Can’t exactly blame the guy for not exactly being thrilled with the idea of squaring off with the God King.

CNN has just released their app for the iPad earlier today, meaning you no longer have to load up Safari (or your favorite RSS reader) every time you want to check up on their latest news updates. Best of all is its price tag – Free. Here are some of the app features:

Choose your view from different navigation options; quickly scan the headlines or immerse yourself in a slideshow

Take part in the conversation by commenting on stories and reading othersâ€™ responses

Share stories on Facebook and Twitter or via e-mail

Save stories for offline viewing

Watch live video streams of breaking news and other major news events

And as an added bonus, the iPhone version of the CNN app has dropped in price to Free (down from $1.99). If you enjoy reading news on your iPad, and CNN is one of the sources you rely on, this is one app you want to grab now from the App Store. Check out the video demo after the gap.

algoriddim, developers of the award-winning djay for Mac, have now released the fully featured djayapp for the iPad. Utilizing the iPad’s 10″ screen and music stored within your library, you can finally scratch and mix all your favorite tunes just about anywhere.

djay transforms your iPad into a fullâ€“fledged DJ system and seamlessly integrates with your iTunes music library, giving you direct access to all your favorite tracks and playlists.

Cut the Rope (TMA Review), one of the most adorable and addictive (not to mention challenging) puzzle games on the App Store, has just received its very first update. In addition to the much welcomed support for Retina Display, the puzzler has also been given a brand new “Cosmic Box” stage, which now includes 25 extra levels and the nifty gravity button (why, it inverts gravity!). Other new features include an optimized scoring system, 11 new Game Center achievements and a new leaderboard for bragging rights.

If you already own this delightful game, be sure to download the update now. If not, you can always check out the free lite versions of Cut the Rope for the iPhone andÂ iPadbefore making the purchase.

Readdle, makers of the trusty ReaddleDocs app, has just updated their PDF Expert for iPad(see our iPhone review) with 2 useful new features. Already able to annotate text and allow for handwritten notes, the app now gives you the ability to include signatures into any PDF file. Rather than have the user scribble them out every single time it’s needed, PDF Expert provides a template area where you can carve out your signature beforehand. Once it’s created, simply tap and hold on the area of screen you’d like for it to appear and choose the option “Signature”. Rinse and repeat. With the template, it eliminates any potential inconsistencies and makes the process much quicker.

In anticipation of the long overdue iOS 4.2 update for the iPad (which will finally bring folders and multitasking to the tablet), Reeder for iPad (TMA Review)Â has just been updated with support for task completion syncing. As such, the app can be closed and your Google feeds will continue to download in the background. Facebook and Zootool are also new additions to the already expansive sharing options. Other changes/fixes include:

Reeder for iPad is arguably the best Google Reader client on the device, and it’s also one of the apps I rely on most on a daily basis. If the $4.99 price tag doesn’t quite jive with your current budget, you can also take a look at the news reader News Pulse, which was just made Free permanently by the developers.
